This item helps avoid danger, but it's also incredibly cute ♡ I bought different sizes for my large toy poodle (8kg), but the smaller one was sufficient, so I haven't opened this one. This glowing collar provides peace of mind during nighttime walks. It's very lightweight and won't put a strain on your precious dog's neck. You can easily adjust the length with scissors. Original price: 1200 yen There's also a YouTube video explaining how to use it. It's a C-type and can be recharged for repeated use. A charging cord is also included. - Brightness: 60.1 lux - Improved safety: Enhanced visibility at night Thank you for looking.
